I would like to say that for the same project, the compiler configuration is exactly the same, optimization level is set to -s, compiler optimization ability is decreasing.  Attached is the comparison diagram of V2.05 V2.10 V2.36.

See https://www.microchip.com/forums/m1208436.aspx for some possible explanations of why this appears to be the case.

Hi all,
Orcad CIS support data base you can use mySQL (free) or MsAccess or any other data base who support ODBC connection

In one of the company's I use to work with ,They have MySql and Orcad CIS worked very well, easy to insert new part using 3rd party software and easy to work with

you can also build a custom components add software and automatic inventory scan to let you know whether components quantity are at limit, using python according to your own needs - simple and easy if to know how to write python script and access data base ....

All the best

Bobi

A part database is always good.
First it is important to use the design software to output proper parts data as explained above.

Improving the lists later can be simply programmed using Python with Pandas.
All data can be processed in an automated way there.

Output formats can be XLSX, CSV and others.

I can definitely testify that fiber laser can make PCB easily.
On my 20W machine I have etched out copper many times and all is good.

The lens focal length definitely have effect on the power transmitted.
With 50mm focal length, I can even cut the boards (very stinky fumes) to odd shapes if required.

I checked the voltage on the VCAP pin and found about 3.3V instead of 1.8V as described in the datasheet.
I find the same voltage on all 3 DSPIC33EPs I have.
Inserting a DSPIC33FJ the voltage is about 2.6V, 2.5V is written in the datasheet.
The DSPIC33EP i I have only used on this test board and I keep swapping the two sets of chips without having any problems on the DSPIC33FJs.

I wonder how much of a nightmare scaling would be over HMDI to that display across devices...

Nothing that cannot be calibrated with a few iterations. Sprint Layout can, for example, scale on X and Y axis a Gerber so it can adjust the print result therefore making it useful for compensation of such LCD presenting scaling errors.

The fuse settings I used are in the source that I attached to the first post (main.c).
There is also the commented configuration for the DSPIC33FJ working correctly.
I don't know Proton, I have installed Proton IDE but I don't have MPLAB 8 to try it, it doesn't seem free to me.

I looked at the oscillator configuration in the source that I attached to the first post, it seems right to me.
The configuration for the PIckit3 is certainly correct because the PIC memory is programmed, erased and read.

Configuration used:
Windows 10 updated
Pickit3 both original and clone
MPLAB X 5.50 and 6.00
XC16 v1.70 and v2.00 free

check the fuse values, surely those for the clock and the one that enables debugging are wrong.
